Answer:
36
Step-by-step explanation:
b= √(c²-a²)
b= √(45²-27²)
b= √(2025-729)
b= √(1296)
b= 36
All three sides of the triangle are the same so youcan set two of the equations equal to each other and solve for x:
4x-10 = 3x +2
Add 10 to each side:
4x = 3x + 12
Subtract 3x from each side:
x = 12
Answer:
-1/6
Step-by-step explanation:
first, we multiply the two fractions in the parentheses to get 1/3.
now we add 1/3 and -1/2 together. doing this we get -1/6
So since this is half a circle, we have to divide the area of a circle by 2. So that would give us 1/2 pi* r^2. We find the radius by dividing 10 by 2. So the radius is 5. Plugging that in for r in 1/2(pi)(r^2) we get 1/2(pi)(5^2) which is 25pi/2. Turning pi into 3.14 we have (25(3.14))/2 which is 78.5/2 which is approximately 39.25 units^2
